Baby tracker features: everything Cocoon does
Cocoon fuses the daily log and the journal — the tracker that also remembers — with nap and feed forecasts, a sleep program, growth charts, reports for the doctor, family sharing and a full export. Every feature is free right now — no ads, no subscription.
Log it in seconds
Feeds, nappies, sleep, pumping, solids and more — one tap each, one-handed, offline.
One-tap logging with Undo
Four tiles that never move — Feed, Nappy, Sleep and Journal. Each one logs the usual in a single tap, half-asleep, with the baby in your other arm.
How it worksBreastfeeding & bottle tracker
Which side was last? How much was in that bottle? Keep the useful details together, with nursing timers and a simple bottle log.
How it worksPumping log & milk stash
Log a pump in seconds, send the milk straight to the fridge or freezer, and always know what's in your stash — and what to use first.
How it worksSolids & allergen tracker
A first-foods picker with the common allergens flagged, a reaction check on every entry, and a clean history of what's been introduced — ready for the next appointment.
How it worksNappy / diaper & potty log
Wet, dirty or both — one tap. Colour, consistency, rash and a photo when you need them. And a gentle potty log for the next stage.
How it worksPrivate drink log
Keep a private record of what you logged, with a link to published information.
How it worksSleep & what's next
Timing estimates from sufficient recorded history, a night-by-night sleep program, and patterns worth exploring.
Next nap & feed predictions
Know when the last feed or wake happened. With enough logs, see a planning estimate and what it is based on.
How it worksSleep tracker, plan & report
Nap and night timers that carry across midnight, the settling details that matter, and a clear picture of the last seven nights.
How it worksSleep program
Choose an approach that fits your family, and Cocoon walks you through it night by night — measuring progress from the logs you already keep.
How it worksInsights, charts & weekly digest
The long-term reason to keep logging: clear charts, a weekly digest with numbers you can trust, and patterns compared with your own baby — never someone else's.
How it worksHealth & growth
Growth percentiles, medicines, temperatures, milestones and reports your doctor can read.
Growth charts & percentiles
Keep measurements together and bring the trend to your next checkup. Recorded growth under two, with CDC reference percentiles from age two.
How it worksMedicine, temperature & health log
When did the last dose go in? Cocoon knows — and warns you before an early one. Temperatures, symptoms, vaccines, teeth and visits, all in one place.
How it worksMilestones & development
Milestones as ranges, not deadlines: the CDC checklist, a gentle “This week” card on Home, and every first saved to the journal.
How it worksCheckup report & PDF summaries
Bring selected records and the questions you want to discuss. Check the dates, note what is missing and let your care team interpret the information.
How it worksMemories
The photo and video journal that sits beside the log.
Family & you
One log for everyone who cares for your baby — and a little care for you.
Family sharing & shift handoff
Give invited caregivers a common record and a clear way to ask someone to take over. A request and a confirmation stay distinct, with delivery status visible.
How it worksParent wellbeing
A baby app that asks how you are. Private check-ins, your nights beside your mood, and help that's close when you need it.
How it worksHands-free & smart
Voice, widgets, the Lock Screen, Siri, reminders and optional AI.
Voice, widgets, Lock Screen & Siri
For when both hands are full: speak it, tap it from the Lock Screen, or ask Siri. Timers and the next window are always one glance away.
How it worksOptional AI assistant
Ask “how has her sleep changed this week?” and get an answer from your own logs, with the data it used shown. Optional, off until you say yes, and never a diagnosis.
How it worksPrivacy & access
Private by design, yours to export, and built for everyone to use.
Private, offline & yours to export
A baby app holds some of the most sensitive data there is. Cocoon treats it that way — and never holds your memories hostage.
How it worksAccessibility, night mode & your units
Readable at 3am, at 200% text, with a screen reader, in your units and your words — because every parent is tired and no two families are alike.
How it worksGuides, importing & tools
The rest of Cocoon: the guide library, the way in from another app, and free calculators.
225 evidence-based guides
Sleep, feeding, nappies, health and development — offline in the app, surfaced when your logs suggest they'll help, and written in your region's words.

Do I need an account to use Cocoon?
No. You can set up your baby and start logging without an account — everything saves on your phone. A free account adds backup, sync across your devices, the caregivers you invite, a second child and the optional AI features.
Which devices is Cocoon on?

Does Cocoon give medical advice?
No. Cocoon is for observation and context, not medical advice, and it isn't a medical device. It gives you clear records and referenced guides, and always points you to your doctor or child-health nurse with any concern. In an emergency, call your local emergency number.
